COIgN-CONTROLLED STEREOSCOPE.

SPECIFICATION forming part of Letters Patent No. 485,567, dated November 1, 1892.

Application tiled February 12, 1892. Serial No. 421,318. (No model.)

To. all whom it may concern,.-

Be it known that I, JOHN RINGEN, a citizen of the United States of America, and a resident of St. Louis, Missouri, temporarily at Frankfort-onthe-Main, Germany, have invented new and useful Improvements in Coin-Com trolled Stereoscopes, of which the following is a specification.

My invention consists in the features of novel construction hereinafter described and claimed.

' Figure I is a longitudinal section of my coin-controlled exhibitor, taken at I I, Fig. II. Fig. II is a vertical section taken at II II, Fig. I. Fig. III is a front view of the upper part of the case or cabinet. Fig. IV is a detail side elevation showing the cam and detent lever,the parts being in position for the tripping of the coin. Fig. Vis a detail section, also taken at I I, Fig. II, showing parts in di'erent position to that shown in Fig. I.

The cabinet or case 1 contains a clock mechanism having a housing 2, consistingof parallel plates secured by'studs 3 to the side wall of the cabinet.

4 is the main spring of the mechanism 5, mounted upon a shaft 6 and operating the first spur-wheel 7, having the usual ratchet connection with the winding-shaft and the gear-wheels of the mechanism, as found in ordinary clockworks.

8 is a shaft carrying three disks 9, l0, and 11, the peripheral outlines of which are seen in Figs. I, IV, and V. The disk 9 serves to make and break the electric connection between the electric accumulator or batteries 12 and the inclined electric light 13. The disk or cam 10 serves to open the cover 14 to the inclined obj ect-glass 15. The disk or cam 11 is a detent-cam, acting in conjunction with the coin-lever to hold the clock mechanism in its normal position of rest. The front of the cabinet has aslot 16, adapted for the pas sage of a coin of desired dimensions. This slot is at the upper end of a coin-chute 17 whose lower end is closed by the end 18 of the coin or detent lever 19. This lever is fulcrumed to the housing-plate at 20, and has a depending arm 21, engaging, when in normal position, the crossarm 22 of the fan 23, by which the speed of the clockwork is limited. This crossarm carries the wings of theA fan and is upon a spindle 24, having a gearscrew 24a, engaginga screw gear-wheel on the clockworkshaft 25. It will be understood that the shaft 25 and fan 23 rotate at a high speed, and the resistance of the airlimits the speed of the clockwork. The device is in is free to turn. The periphery of the cam.

disk 11 has a projection 27, that acts on the pin 193J and throws down the end 18 of lever 19 until a standing pin 28 passes through an opening in the end and tilts the coin 0E the end 18. (See Fig. IV.) As the pin leaves the projection 27 its descent is limited by the periphery of the cam-disk and is not allowed to descend until the rotation of the disk brings the notch 26 beneath it, when it drops into the notch and arrests the motion of the clockwork. The cover 14 of the object-glassY 15 is open during the movement of the clock mechanism, so as to allow a person during that time to look through the glass into the cabinet. To accomplish this the cover is pivoted at 29 and attached to an arm 29a, connected by a rod 30 to one end of a lever 3l,fulcrumed at 32 to the housing, and carrying at the inner end a pin 33, that is in contact with the periphery of the cam-disk 10. The form of this peripheryis such that when the cam 11 begins to turn the cam 10 lifts the inner end of the lever 31 and throws up ,the cover 14 and keeps the cover in this position until the cams reach their normal position, when the inner end of the lever 31 descends and the cover 14 closes over the object-glass 15. (SeeFig. I.) When closed the cover displays a placard of instructions for operating the stereoscope. The lower part of the cabinet contains one or more electric accumulators or galvanic batteries 12.

The conducting-wire 34 leads to a terminal IOO spring 35, that is insulated at its point of attachment 35 with the metal housing. This terminal spring is in contact with the periphery of the metal disk 9 While the clockwork is in motion; but when the parts are innormal position the spring is not in contact with the disk, the disk being notched at 9 to prevent contact when in this position. The spring 35 being one terminal, the disk 9 is the other, an incandescent or other electric light 13 being in circuit.

34 is the part of the conducting-wire between the accumulator and the electriclight, and 341 the conductor between the light and the metal plate with which the disk 9 is in contact. This serves to illuminate the pictures While the cover is open. The pictures 36 are carried on brackets 37, attached to an endless belt 39, carried on three rollers 40 4l 42. The shaft 43 of the pulley 40 ends in lthumb-knobs 44 outside the cabinet, by

which the roller may be turned and the whole belt revolved to exhibit one picture after another as each in turn comes in line with the object-glass and with the rays of light projected by the reilector behind the electric light. The brackets 37 are connected to the belt 39 by a fiat base 3S, extended in both directions, the connection between the base and the belt being made on a transverse line immediately beneath the edge of the picture, so that the belt may leave the edges of the base when passing over the rollers, as seen in Fig. I, while the picture stands out at right angles to the belt when between the rollers. YVhile the picture is passing from roller 41 to roller 40, it is inclined and in direct line with the inclined object-glass and in the rays of light, so that the picture can be arranged in the proper focus for the eye of each patron.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The combination of the rollers, the end less belt carried by the rollers, and the picturebrackets having secured to the belt fiat bases extending in both directions, substantially as described.

2. The combination of the casing havingv a coin-slot, the coin-chute, the clock mechanism having fan-arms, the shaft rotated by the clock mechanism having cam-disk 11 formed with a notch, the coin-lever having one end normally closing the lower end of the coinchute and the other end provided with a stud normally occupying the notch of the camdisk, the standing pin located beneath the outer end of the coin-lever, and means for releasing the clock mechanism for rotating the cam-disk, substantially as described.

3. The combination of the casing having a coinslot, the coin-chute, the coinlever, the objectglass, the pivoted cover having an arm, the connecting-rod, the cover-lever, the clock mechanism, the shaft rotated by the clock mechanism, the cam-disks 11 and 10, secured to the shaft, the rollers, the endless belt, the picture-brackets on the belt, and means for releasing the clock mechanism for rotating the camdisks, substantially as described.

' In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN RINGEN.
